-- The north through lanes Old Dominion Drive will be closed between 22nd and 26th Streets North between 9:30 a.m. and 3 p.m. due to maintenance work.

-- The west right lane of Dulles Toll Road/267 will be closed from Beulah Road to Hunter Mill Road from 9:30 a.m. to 3 p.m. due to maintenance work.

-- There's an accident on 395 Southbound at Maine Avenue in Southwest, so be aware of potential delays.

-- There's also an accident on the 14th Street Bridge, so again, be wary of delays. Traffic on the bridge is moving sluggishly, but not moreso than usual at this time.

8:55 A.M. UPDATE:

-- The B.W. Parkway/MD 295 has reopened all lanes in both directions, said Sgt. Schlosser. The southbound lanes were closed for the entire morning and one northbound lane was closed in the aftermath of the early morning accident. Expect residual delays as traffic gets back to normal.

-- There's a disabled vehicle on I-495 North at the Leesburg Pike, closing the right lane.

-- I-395 North delays and congestion continue from the earlier accident on the 14th Street Bridge.

-- Traffic signals are out at 10th Street and Michigan Avenue in Northeast, so that intersection will be slow and sluggish.

-- Fire and emergency activity in the 1100 block of C Street in Northeast is impacting traffic.

-- An accident at 14th and Oglethorpe streets in Northwest is slowing traffic.

8:25 A.M. UPDATE:

More information on the accident that caused the B.W. Parkway closure this morning: A car heading southbound on the B.W. Parkway left the road at about 3:45 a.m. and crashed into an object in the median, said Park Police spokesman Sgt. David Schlosser. It occurred just north of MD 193. The driver was pronounced dead on the scene after being removed from his car by Prince George's Fire and Emergency Services. He was identified only as an adult male because his family has not been notified yet. There were no other vehicles involved in the accident.

The southbound lanes are going to remain closed until at least 8:45 a.m. while officials are on the scene investigating, Schlosser said. There is one northbound lane open at this time.

8:05 A.M. UPDATE:

-- MD 295 and U.S. 29 South both remain closed in Maryland.

-- An accident at New York and Montana avenues in Northeast might slow traffic. Ditto an accident on the 1700 block of S Street in Northwest.

-- I-395 North traffic remains terrible from the bridge on back, so expect major delays if you're taking it this morning.

-- Traffic remains heavy on I-495 North (leading to I-66) and on I-66 (leading to the Beltway).

-- An accident on I-95 South/the Beltway at Telegraph Road has closed the southbound left lane. Expect delays.

7:35 A.M. UPDATE:

-- B.W. Parkway/MD 295 remains closed southbound at MD 193. One of the two northbound lanes is still closed.

-- An incident involving two cars has closed U.S. 29 South before Greencastle Road in Burtonsville. (This stretch of the Columbia Pike runs parallel to MD 295, which is also closed southbound; but this particular closure is right next to I-95.)

-- The 14th Street Bridge accident occurred on the bridge heading inbound (northbound) in the H.O.V. lanes, according to Kenny Bryson, spokesman for the District Police Department. There were several vehicles involved and several people complained of minor injuries, he said. The District police are on the scene and hope the lanes will be cleared up soon. The Arlington County Fire Department is also on the scene, according to an official with the county.

-- That accident is causing major backups and gridlock from the bridge to the Springfield Interchange. Traffic cameras show a sea of taillights, unmoving in some spots or barely edging forward in others. If you can avoid this route (possibly by heading north to I-66 East and taking the Teddy Roosevelt Bridge), we highly recommend it.

-- Traffic is also getting bad on I-66 East from Chain Bridge Road and stretching back for a while.

6:45 A.M. UPDATE:

-- The accident on I-395 North at the 14th Street Bridge is causing backups as far back as Washington Boulevard, and congestion for most of the roadway before that.

6:30 A.M. UPDATE:

-- All of the southbound B.W. Parkway/MD 295 lanes remain closed, as does one of the two northbound lanes.

-- An accident on I-395 North at the 14th Street Bridge has closed the north right lane.

-- There's also congestion already building on I-395 North at the 14th Street Bridge and King Street.

6 A.M. UPDATE:

One of the northbound lanes on the B.W. Parkway/MD 295 has reopened. All of the southbound lanes, and one northbound shoulder, remain closed.

ORIGINAL POST:

An accident earlier this morning on MD 295/Baltimore Washington Parkway South at MD 193/Greenbelt Road has closed MD 295 in both directions. This closure occurs just east of where MD 295 and the Beltway intersect in Greenbelt, and will cause major congestion.
